An optical arrangement for ascertaining the orientation of an artificial lens in an eye comprises an observation beam path with an imaging optical system, at least two light-emitting test objects with a defined contour, and one collimation optical system paired with each test object for collimating the light pattern emanating from the test object in a collimation beam path that is directed at the eye. The imaging optical system is designed such that said optical system has multiple observation beam paths with different imaging properties in order to simultaneously image multiple reflected light patterns from different depths of the eye, or the imaging properties of the observation beam paths can be adjusted in a variable manner in order to be able to sharply image sequentially reflected light patterns from different depths. |
